SMALL TO MEDIUM DIAMOND SIZE
The D41 is typically set with 4 to 12 stone-per-carat natural diamonds for drilling hard, dense formations with high compressive strengh and moderate abrasives. It can be used in both motor or rotary applications.

CROWN PROFILE
The ”B” profile maximizes diamond concentration across the nose to ensure even diamond wear. Transition zones across the face of the bit are reduced, preventing excessive point loading, minimum cutter breakage and better performance in hard, abrasive formations.

FEEDER/COLLECTOR HYDRAULICS
The D4 is designed with cross pad flow for maximum cooling of the diamonds. Fluid is drawn across diamond pads from high pressure feeders into the low pressure collectors. This configuration allows greater diamond density across the nose to improve bit life.

NATURAL DIAMOND GAUGE
Because of their exceptional wear resistance, natural diamonds are used for gauge protection. This feature ensures consistent hole size is maintained throughout the entire bit run. A full gauge hole eliminates reaming and makes sure that this are not damaged and do not become stuck on subsequent trips.

INPREGNATED DIAMONDS
These bits utilize a unique process where diamond cutters are aintered into a tungsten carbide matrix whose composition is matched to the formation to be drilled. Impregnated designs continually expose a sharp cutting edge and are designed to drill medium hard to the hardest, mast abrasive formations at a variety of rpm, including rotors, PDMs and turbines.

RADIAL FLOW HYDRAULICS
Radial fluid flow assures efficient cuttings removal and minimizes premature increase in bit wear. Fluid flowing from the bit's axis towards the shoulder through a series of parallel and expanding fluid courses cleans and cools the diamonds more efficiently.

MATRIX BODY
Bits constructed with tungsten carbide matrix bodies are tough and extremely resistant to erosion and abrasive formations. High pressure drops across the bit face, ling bit runs and a higher solids content in the mud are possible with this bit body material. In addition programs to be optimized for each application.
